Acute ethmoiditis complicated by intraorbital abscess, orbital cellulitis, and cerebral empyema in a 14-year-old girl.

We report the case of a 14-year-old girl with pain and protrusion of the left eye and treated with diclofenac. Clinical and paraclinical examinations revealed a cerebral empyema and a left retro-orbital abscess complicating an acute ethmoiditis. Parenteral antibiotic remains essential in the management of acute ethmoiditis to prevent complications.
